Tangosol Coherence Continuous Query
For those who don't know, one of the aims of Bhavaya is to allow for users to specify the data they want as criteria (which is ultimately translated to sql queries, much like Hibernate), the library will then return a collection of beans matching this criteria and then keep this collection current as data in the database is changed, for example, beans may be inserted, updated or deleted from the collection. The collection fires events to listeners to inform them of changes to its elements. Bhavaya focuses on efficiency, by applying deltas to the collection without hitting the database again, this allows for efficient distributed, observable caches of data.
